A study of highly activated hydrogen evolution reaction performance in acidic media by 2D heterostructure of N and S doped graphene on MoO_<i>x</i>

Abstract Herein, a layer of molybdenum oxide (MoO x ), transition metal (TMO), which has outstanding catalytic properties in combination with carbon‐based thin film, is modified to improve the hydrogen production performance and protect MoO acidic media. A film graphene transferred onto layer, after structure doped N S atoms at room temperature using plasma doping method modify electronic intrinsic material. The oxygen functional groups increase interfacial interactions electrical contacts between . appearance surface defects such as vacancies can result This improves conductivity electrochemically accessible area. Increasing number by adding dopants significantly affect chemical reaction interfaces electrochemical performance. These play crucial role adsorption H + ions on their transport underneath. enables participate graphene.
